Rather than retype it again here, here is a link to the results of trying Caswell's brightener.

All of the talk these days around the Bay Area is about hydogen embrittlement issues causing bolts to break on the new Bay Bridge. Thought it tied in with this topic nicely!

Hopefully all of our replated parts don't start snapping :-)

It was a concern of mine when I started doing this. The problem only attacks high strength steels like grade 8 bolts, springs, spokes, etc. The trick for those is to bake at 350F for a half hour after plating to drive out the H2.

I spoke with the engineer from International Plating and that is what he recommended and what they do when they chrome plate those types of parts.

One of the thoughts is that the acid baths used in the plating process for commercially plated parts impart my H2 into the grain structure than the plating process.

The spokes on my CL77 are in their 3 year and still doing fine. All were baked after plating.
